UST Air Conditioning is the heating tune-up company Halaula residents call first. Our technicians arrive the same day in most cases, diagnose the real problem and complete most heating tune-up jobs on the first visit.
Because we work in Halaula every week, our technicians know the equipment common to the Big Island homes, the corrosion the trade winds cause and the parts that fail first. That local experience means faster diagnosis, fewer return trips and repairs that last.
Whether you are in a single-family home, a condo with strict HOA access rules or a vacation rental with guests arriving, UST Air Conditioning coordinates the heating tune-up appointment with whoever needs to be involved and leaves the space clean.
The Big Island asks more of a heating and cooling system than any other island. Halaula homes deal with humidity and salt near the coast, vog drifting from Kilauea, and cool nights at elevation where a heat pump earns its keep. We size and service equipment for that range.

The technician found that our ducts were leaking into the attic, which explained the hot back bedroom. Sealing them made a bigger difference than I expected and our bill dropped noticeably.
Michael S., HalaulaThe mini-split in our bedroom kept dripping down the wall. Two other companies never called back. UST came the next morning, cleared the drain, cleaned the coil and showed me photos of the mold they removed.
David W., HalaulaWe manage several vacation rentals and needed a company that would coordinate with guests and send invoices to us. UST has been reliable, on time and fair on price every single call.

Yes. Mini-splits are our most requested installation on the Big Island because they cool individual rooms efficiently without ductwork and many models also heat.
Most common repairs, such as capacitors, contactors, drain clearing and fan motors, fall in a modest flat-rate range that we quote before starting. Larger repairs like compressors or coils are priced against replacement so you can decide. There are no hidden fees.
